QR codes are applied widely on the Internet and mobile devices in recent years. Its open standards and the characteristics of easy to generate lead to anyone can generate their QR code easily. Also, the QR code does not have the ability of hiding information, which leads to everyone can get access to read the content in any QR code, including those hiding some secret content in the bytes of QR code. Therefore, in recent years, information tampering and information leakage cases caused by poor security of two-dimensional code occur frequently, especially in the financial field and multi-party verification scenarios. QR codes are almost impossible to use in these scenarios. Therefore, this paper proposes a distributed information sharing method based on information hiding QR code. This method can make secret code in QR code safer and robust, and the secret shared between receivers can be used for decryption and attacking detection. Therefore, on the one hand, the information hiding method can maximize the capacity of embedded secret information, on the other hand, it can prevent attacks by disguised attackers and recover hidden secret information through reconstruction. This paper illustrates the feasibility of this scheme through the form of theoretical proof.
